Installing software from a newly added repository does not work

[AsciiWolf <mail asciiwolf com>]

Hello,

there is one bug in GNOME Software on Fedora that is making me sad and is the reason why I cannot recommend Fedora to any of my non-IT friends or family members. If an user adds any new repository, for example RPM Fusion, and then tries to install some software that is present in the repository using GNOME Software, he gets a "Enable Third-Party Software Source?" dialog, however clicking on "Enable and Install" does nothing, leaving the user without any possibility to install the third-party software in a user friendly way. This also includes no user-friendly way of installing codecs or NVIDIA drivers.

Here is a link of the original bug report and more information from Christophe Fergeau:

It would be great if this bug could be fixed. Unfortunately, I am personally not a programmer so I cannot do it myself.

Thanks!

Regards,

Daniel Rusek
